According to USA Today, the ketogenic diet involves consuming a low carbohydrate, high fat and high protein diet. Out of the total daily caloric intake, nearly 70 to 80 per cent comes from fat, 20 per cent from protein and the remaining 5 per cent or so are derived from carbohydrates. The carbohydrate deprivation pushes the body into ketosis, which is a state where fat becomes its primary fuel source. Despite its ability to cause rapid weight loss, this dieting approach doesn't find many supporters among medical professionals. The Keto diet is usually not recommended by doctors for the reason that it excludes a wide array of essential food groups that are imperative for optimal health, such as grains, fruits, and some vegetables. Medical professionals caution people to be aware of the difference between weight loss and overall health.
